The B + W 77mm 110 Solid Neutral Density 3.0 Filter has several uses and offers the possibility to achieve otherwise unachievable results. ND filters appear gray and reduce the amount of light reaching the film. They have no effect on color balance. Neutral Density filters enable the shooter to adjust exposure without affecting color balance. ND filters appear gray and reduce the amount of light reaching the film. Neutral density filters are available in 1, 2, 3, or 4 stops to suit individual situations.Neutral Density filters permit you to create unique effects. When using high speed film in bright light, an ND filter will allow you to blur motion such as speeding cars or moving water. This permits adjustments in aperture and exposure that would normally not be possible without the filter. Determining which neutral density filter yields ideal results for any given lighting situation takes knowledge, experience and a collection of such filters. Speaking generally, the 2-stop value (ND 0.6) effectively compensates average situations.The reputation of B+W's Schott glass is world renowned. The high production standards combined with a sturdy brass filter ring make B+W filters hard to beat. These filters have a inheftin to them that is impressive. They may feel heavier but the benefit is in the construction and results. Not only is the glass exceptional but so is the seal between the ring and glass. Schott Glass used in the manufacture of this filter is legendary an
- Neutral Density 3.0 (exposure adjustment = 10 stops, transmits 0.1% of light)"
- To allow cine and video cameras (which have fixed shutter speeds) to film subjects such as snow, sand or other bright scenes which could cause overexposure
- To decrease depth of field by allowing wider apertures to be used, which helps separate subjects from their background
- To decrease the effective ISO of high speed film (above ISO 400) and allow it to be used outdoors in bright situations
- To enable slow shutter speeds to be used, especially with high speed films, to record movement in subjects such as waterfalls, clouds, or cars
